Hang on, when someone is posting a listing which shouts "GENUINE" and then you get clearly non-genuine item in hand, how would you name it? I call it a "lie" and that definitely deserves a negative feedback to be posted. Simple as that.

These styluses came in small bubble envelope, without original packaging, just wrapped in little foil - that's fake indicator number one. When you take original N900 stylus in hand and compare with "genuine" one that came round from ebay you'll see evident fake indicator number two - low quality, softer plastic and Nokia logo slightly differently embossed. Thankfully they fit the slot perfectly.

Btw, I don't mind buying non-genuine items, as long as I know beforehand these aren't genuine. Otherwise I post negative straight away.
